Sequential circuits samplers

Yes, I unplugged the connector for a better look in the picture.  In
both photos it is the same wire it just goes from the connector to the
main board and I couldn't tell if it was supposed to be there or if
someone had added it for some reason.

It does not function at all.  I bought it knowing this.  I went to
replace the fuse, thinking I would get lucky and it instantly blew and
keeps blowing all fuses I put it with no sign of life.  However, if I
put a slow blow fuse in, then I see some life from the floppy drive,
but again the fuse just blows.

I was hoping that it was not the power supply as I do not know how to
test those components (I suppose that it wouldn't be hard and I could
do it if I knew exactly which components to test, but I do not have a
service manual or schematics so it is difficult).

Thank you very much for your time and I would very much appreciate the
photos if you can make time.

Thanks.
